Title: Improvements in or relating to control valves for automatic air brakes
IPC: B60T15/18
Filed: 1926-04-12
Abstract: 250,936. Forte, G. April 16, 1925, Convention date]. Void [Published under Sect. 91 of the Acts]. Fluid-pressure.-A distributing valve for automatic compressed-air brake systems comprises control pistons subject to the pressures existing in the train-pipe, the auxiliary reservoir and the brake cylinder whereby a definite pressure is established in the brake cylinder dependent upon the reduction effected in the train-pipe pressure. A piston b subject to the opposing pressures in the train-pipe and auxiliary reservoirs by passages d and h actuates a slide valve g controlling ports m, l open respectively to the atmosphere at p and to a chamber n in which work a pair of pistons q, r. The piston v is constantly subject on the one side to the train-pipe pressure by passage f. and on the other to atmosphere by the passage 8 and port p. In running conditions as shown, the train-pipe charges the auxiliary reservoir i through a groove k past the piston b and the slide valve g connects the chamber n to atmosphere by ports l, m, p so that the pistons q, r are held in the raised position by the train-pipe pressure whereby the brake cylinder is open to atmosphere by passage 11 and ports v, x. If the train-pipe pressureis reduced the slide valve g moves to uncover the port l and admit auxiliary reservoir air to the chamber n so that the pistons q, r descend and the piston g closes the brake cylinder exhaust port x and opens a port u by which air is supplied from the auxiliary reservoir to the brake cvlinder. When the difference in auxiliary reservoir and brake cylinder pressures is equal to the reduced train-pipe pressure the piston q, r moves upwards to a position in which the supply and exhaust ports u, x of the brake cylinder are both closed. The brake cylinder pressure can be increased or diminished by effecting a corresponding variation of the train-pipe pressure. The upward movement of the pistons q, r from the neutral position is opposed by a spring 2.

Filed: 1953-04-10
Abstract: 725,008. Abrasive band machines. BOSTON WOVEN HOSE & RUBBER CO. April 10, 1953, No. 9773/53. Class 60. A machine for grinding a flat endless steel band 10, Fig. 2, such as that employed in a continuous vulcanizing machine, comprises two rotary drums 16, 18 to support the band, bearings 27, 30 to support the drums, removable supports 29 for the bearings at one side of the machine to permit replacement of the band, an endless abrading belt 58, and means for traversing the belt along a rotating roll 56, Fig. 1. The band is driven by the drum 18 and placed under tension by the drum 16, the bearings 30 of which are displaceable in guides 32 by hydraulic pressure. Each pair of drum bearings is bolted to a cantilever support 22 providing a gap 25, Fig. 4, for the passage of the band 10 while the roll 56 is journaled in two supports 38 pivotally connected at 40 to the base 20 of the machine and held in operative position by pneumatic pistons 42. Screws 48 and handoperated worm drives 54 permit independent adjustment of the supports 38. The roll 56 is driven by a motor 68 and the belt 58 traversed along it by a screw-propelled carriage 62 provided with pneumatically loaded idler rolls 60 and 72 for the belt 58 and a cushioning belt 71. The inside surface of the steel band is simultaneously abraded by a belt 94 operated in the same manner as the belt 58 and co-operating with a drum 80 journaled in a frame 81 pivotally connected at 82 to the machine base 20, grinding pressure being applied by pneumatic pistons 83. Scrapers 36 clean the drums 18, 80 and the faces of the steel band. The abrading belts are automatically withdrawn from the work if the load on their driving motors exceeds a predetermined value. This is accomplished by a solenoid-operated valve which cuts off the air supply to the pistons 42, 83 and connects their cylinders to exhaust when relays in the motor circuits are operated by the increased current. These relays also operate a holding circuit so that a manually-operated switch has to be opened before the belts can be returned into contact with the work.

Title: Improvements appertaining to doffing mechanism for flyer spinning, doubling, twisting and like machines
IPC: D01H9/04
Filed: 1928-05-31
Abstract: 322,450. Fairbairn, Lawson, Combe, Barbour, Ltd., Lawson, L. H., and Porter, J. A. May 31, 1928. Divided on 322,196. Doffing-arrangements; stop-motions; building- motions; stop-apparatus non-automatic. - In spinning, doubling, twisting, and like machines of the kind wherein duplicate lifting rails are used and interchanged for doffing purposes, means are provided whereby the mechanism for moving the lifter rails can only be operated when the lifter bracket is at or near the top of the lift or below the lower limit of the lift, and to stop the machine after it has been restarted if the doffed rail has not been removed from 'beneath the rail in operation. The invention is described as applied to the doffing-mechanism described in Specification 322,196. A wheel 8 is mounted on a shaft 9, Fig. 2, by which the gear for moving the duplicate rails during doffing is operated, and is normally engaged by a spring- controlled bolt 6 except when the rack 4 of the lifting rail is lowered for the removal of the fully wound bobbins and a bowl 6a on the, tooth enters a recess 5b in a plate on the rack, and when the - racks are raised in restarting or to effect the winding of coils on the bobbin and the bowl enters a similar recess 5a, as shown in Fig. 2. The bowl is enclosed in a casing and the projection of a rod 6w therefrom indicates that the bolt is engaged with the wheel 8 and that the apparatus should not be operated. During the release of the wheel 8 when restarting the operative should operate the mechanism so that the doffed lifting rail 2a is removed to the rear as shown in Fig. 7, but should this operation be omitted a projection 16<d> from a bar 16, on which the rail 2a would be resting, operates a lever system 19, 20 and moves a spring-controlled rod 22 which projects a pivoted bolt 25 into the path of the operative rail 2 in its normal descent during the winding of the bobbin. When engaged by the descending rail, the bolt 25, through the link 26, operates a lever 27 and thereby releases a spring-controlled bolt 28 which actuates the belt-shifting bracket 30 and releases a brake band 33 whereby the machine is stopped and the driving-pulley braked. The belt-shifting bracket and the brake band may be manually operated by a handle 34, shaft 35 and lever 36. When a building-motion of the " rat-trap " type is used, wherein stops 41, 41<w>, Fig. 5, on the lifter rack operate a lever 40 which controls the reversing gearing, the stop 41 is moved by a spring out of range of the lever 40 when the lifter rack is lowered for doffing purposes, such movement being permitted by a recess 42a in a control plate 42 which, during the normal lifting movements, maintains the stop 41 in position.
